JP2002195486A - Protection cover of pipe connecting clip - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a protection cover of a clip for connecting pipes to be engaged with the clip in a narrow place such as a toilet while keeping the strength. SOLUTION: Flanges are formed both at the end of a connection pipe and a connected member to be connected to the connection pipe. The flanges are superposed and bound together with a clip. In connecting the pipe, the protection cover is slidable on the outer surface of the clip, and is cylindrical from the flat plane view to be opened/closed to the left/right. The protection cover can be locked after covering the clip.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective cover for a pipe connection clip for retaining a connected member when connecting a water supply pipe.

[0002]

2. Description of the Related Art As a cover for preventing a clip of this type from falling off, there is a cover disclosed in, for example, Japanese Patent Application Laid-Open No. 10-246387. That is, the flange provided at the pipe end of the connecting pipe and the flange provided at the pipe end of the connected pipe are overlapped with each other. A clip is attached and a part of the overlapped flange is inserted into a long hole provided in a main body portion of the clip so that connection pipes do not come off from each other. There has been proposed a fall prevention cover for preventing falling off.

[0003]

By the way, the fall prevention cover of the conventional product is covered according to the shape of the clip. In other words, to install the fall-prevention cover on the clip, first fit the fall-prevention cover to the folded portion of the clip, and then cover the opening of the clip while holding both ends of the fall-prevention cover, Must be locked at both ends.

That is, when connecting pipes in a narrow space such as a toilet space, a cabinet for a vanity table, a cabinet of a system kitchen, or the like, the direction of covering the fall-off prevention cover is limited to a single direction. Depending on the fitting direction, it is necessary to change the direction of the clip in order to cover the fall prevention cover, which may make it difficult to attach the fall prevention cover.

Further, in the conventional product, since there are two hinge portions, there is a problem that the holding strength is uneasy, and if the half-split body is distorted, it cannot be fitted properly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and enables a clip to be fitted accurately even in a narrow space such as a toilet space, a vanity cabinet, a system kitchen cabinet, or the like. It is an object of the present invention to provide a protective cover for a pipe connection clip that can maintain strength.

[0007]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a flange is provided on both a pipe end of a connecting pipe and a connected member connected to the connecting pipe. In a pipe connection in which these flanges are overlapped with each other and the flanges are constrained by clips, the clips are slidable on the outer peripheral surface and open / closed to the left and right in a plan view cylindrical shape. It is configured to be able to stop.

Therefore, the cover can be easily attached even if the clip restrains the flange in any direction.

In addition, since the minimum inner diameter of the protective cover (the portion where the outer peripheral surface of the clip is in contact with the inner peripheral surface of the protective cover) is the outer diameter of the clip, if the clip is not properly fitted to the flange of the connecting pipe, Even in this case, since the clip is firmly fitted to the flange of the connection pipe by the pressing of the protective cover, there is no need to worry about water leakage due to a construction failure.

Further, since the protective cover is made transparent or translucent, the presence or absence of the clip and the fitted state can be confirmed without removing the protective cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing pipe connection using the protective cover of the present invention. In the figure, reference numeral 5 denotes a water supply pipe connected to the socket 6, and a flange 7 is formed as a connection part at an open end of the socket 6. Further, a joint 8 as a male side connected to the socket 6 is provided.
Is connected to a resin pipe 9, and a flange 10 facing the socket 6 is formed substantially in the middle of the direction in which the resin pipe 9 is not connected. Further, an insertion portion 12 having two O-rings 11 to be inserted into the socket 6 is formed at the open end of the flange 10.

In a specific pipe connection method, the insertion portion 12 of the joint 8 is inserted into the insertion portion 15 of the socket 6 so that the flanges 7 and 10 face each other. Next, the clip 13 is attached so that the long hole 14 of the clip 13 is fitted to the outer periphery of both flanges 7 and 10, and the protective cover 1 is covered so as to cover the outer periphery of the clip 13 to prevent the clip 13 from falling off. You do it. Even if the clip 13 is not properly mounted on the flanges 7 and 10, the minimum inner diameter of the protective cover 1 is set to the outer diameter of the clip 13. It will be mounted well.

FIG. 2 is a perspective view showing the closed state and the open state of the protective cover 1. As shown in FIG. 2 (B), the protective cover 1 includes a left half body 2 (a) and a right half body 2 (b),
Lock receiving portions 4 and locking portions 3 are formed at the ends of the two halves 2 (a) and 2 (b). That is, the inner surface of the protective cover 1 is brought into contact with the outer periphery of the clip 13, and the locking receiving portions 4 and the locking portions 3 of the two half bodies 2 (a) and (b) are fitted together to set the protective cover 1. (See FIG. 2A). Thus, the locking part 3
Is inserted into the opening of the lock receiving portion 4 and locked, so that the protective cover 1 does not come off, so that the reliability of mounting the clip 13 is enhanced.

Since the protective cover 1 is formed in a cylindrical shape in a plan view without a projection, there is no possibility of accidental injury during operation.

3 and 4 are a perspective view and a longitudinal sectional view showing a state in which the protective cover is attached to the connecting pipe. The flange 7 of the socket 6 is connected to the flange 10 of the joint 8 so as to face each other, and the clip 13 is attached so that the flanges 7 and 10 are fitted into the long holes 14 of the clip 13. It is.

When the protective cover 1 is set, the protective cover 1 is formed in a cylindrical shape in a plan view, so that the protective cover 1 can be set from any direction regardless of the mounting direction of the clip. .

Further, by making the protective cover 1 transparent or translucent with resin or the like, the presence or absence of the clip and the fitted state can be confirmed without removing the protective cover.

Further, it is needless to say that the clip 13 compatible with the protective cover 1 is not limited to the shape shown in FIG.

The present invention is embodied in the form described above, and has the following effects. That is, in the present invention according to claim 1, a flange is provided on both the pipe end of the connecting pipe and the connected member connected to the connecting pipe, these flanges are overlapped with each other, and the flanges are restrained by clips. In connection, the outer peripheral surface of the clip is slidable and has a cylindrical shape in a plan view that can be opened and closed right and left, and is configured to be able to be locked after covering the clip. Therefore, even if the clip restrains the flange in any direction, the cover can be easily attached. In the invention according to claim 2, the minimum inner diameter of the protective cover is set to the outer diameter of the clip. Since the clip is firmly fitted to the flange, there is no need to worry about water leakage due to construction failure. In the invention according to claim 3, since the protective cover is transparent or translucent, the presence or absence of the clip and the fitted state can be confirmed without removing the protective cover.
